Hi
We do have cisco wireless network in place and our subnet is on IP 10.14.112.0/22 and our organisation users laptops get connected through the cisco wireless network and our DHCP server assigns the IP for devices on our network.

We have a company who has hired one of a room in our organisation for a year.There are 15-20 users who will be using this room for training purpose and they want access to wireless in this room . This company has given me a BT BusinessHub-755 and I want to connect this router to our network and create a separate wireless network for them.
I am thinking of using a separate SSID and want the router to issues IP addresses to the Tablets on a different range rather than our DHCP assigning IP addresses to their devices.
Please suggest will I be able to achieve this or will I have to but a separate access point.

Seems as though BT Business Hub current version 3 does not support multiple SSID. As suggested in the link, you can add another wireless router if you want to separate that new LAN segment. This is not the prettiest method.

From your post, it seems as you are stating you have a DHCP server correct?

The prettiest method would be to have the BT router and another new Wifi Router for the tablets both be set to replay DHCP requests to your DHCP server from which you can create scopes for both LAN segments and corresponding firewall rules if you need to segregate those LANs from your primary Cisco wireless LAN segment.

From my understanding is I need to have two wireless router and one router connected to our network with astatic IP and this router will do the NAT and another wireless router connected to this router , acting as a DHCP and assigning the IP address to the tablets.
Where do I need to create DHCP scopes
Please correct if I am wrong \post some tutorials.

This will be demonstrated using Intel(R) Centrino(R) Wireless-N 2230 wireless card on Windows 8 operating system.
